Accessories
Actuator:
Sauter ASM115SK005, ASM124SK002, 24 V AC, standard
actuators depending on size.
Other actuators must be ordered, see actuator table page 3.
Wiring diagrams are displayed on page 2.
Knob:
CRTT-1 for manual control.
Quick connection:
FSR. Clamp with quick-acting lock.
Installation
Insert the damper into the connecting duct and fix it in
position with blind rivets or by means of an FSR clamp.
See Figure 1.
Commissioning
The damper has no measurement function of its own.
Turn the damper blade at the desired position and lock it.
Maintenance
Clean the damper whenever needed by means of a vacuum-
cleaner and brush nozzle or by wiping surfaces with a cloth.
Figure 1. Installation. Figure 4. Installation of actuator CRT, size 500 and 630. First,
close the damper entirely, then install the actuator exactly
straight and lock it against the damper shaft. Turn the actuator 5°
past closed setting and lock the position of the actuator.
